My internal service recently being crashed by an unknow traffic coming from our local network
The symptom is, there is a significant traffic pushing to service, make the load spike up in sudden and the service is down. The traffic comes in very fast, in just 1-2 minutes so I don't have enough time to remote into the server and tracing
So my question is:
- any command to indicate the top most external IPs which consumes the most bandwidth on the server
- so that I could do a loop to running it every 10-15 seconds or so
I'm running on Ubuntu 18
Thanks in advance
